X-PPL-26: Crosslinguistic Perspectives on Processing and Learning

23–25 September 2026, Bayonne (Basque Country)

The Crosslinguistic Perspectives on Processing and Learning Workshop (X-PPL) brings together the growing community of researchers working to expand the diversity of languages in the scope of psycholinguistics and the neuroscience of language. The research of this community is driven by the recognition that structural/typological and socio-cultural diversity provides important and unique opportunities to see language processing and language learning mechanisms at work and to gain deeper insights into the balance between universal and varying dimensions of these mechanisms. The bulk of processing and acquisition research represents only a small fraction of linguistic diversity, which risks biasing both our theories and our research questions.

The Crosslinguistic Perspectives on Processing and Learning Workshop (X-PPL) aims to overcome this bias and to fill a gap in the conference landscape by providing a platform for cross-linguistic research on language processing and learning.

X-PPL 2026 will be hosted by the AHAL Aquitaine Multilingual Lab (IKER-CNRS), at the University of Pau campus in Bayonne, and will take place on September 23–25, 2026.

The keynote speakers for this edition are:

This year’s SNL annual meeting will take place in Geneva in the week following X-PPL (30 September–2 October). Bayonne is conveniently connected to Geneva by both train (via Paris, approximately 8 hours in total) and by air (direct flights of around 1 hour), facilitating attendance at both meetings.

Submit an abstract

We are now accepting abstract submissions for X-PPL 2026. We invite submissions on any topic on language processing and acquisition which take into account typological diversity and lesser-studied languages.

➡️ Authors are invited to submit their abstracts through x-ppl-26.sciencesconf.org by April 30.

Submission

Before you can start the submission process, you need to create an account via the SciencesConf website. Please contact the organisers if you experience any difficulties or have any questions: x-ppl-26@sciencesconf.org.

Guidelines

Abstracts should be submitted as a single PDF and should not exceed 500 words or one A4 page, 12 pt font size (plus one optional additional page for interlinear-glossed examples, references, and figures). The language(s) studied should be mentioned in the abstract. The scientific committee will then select contributions for 20 min talks.
